Billy Gilman invited four of his friends and former fellow The Voice Season 11 contestants back to the TV singing competition on Tuesday night (Dec. 13), to perform Ike and Tina Turner's "Proud Mary" during the finale.

Readers can press play above to see Gilman team up with Christian Cuevas ("He has such a humble, kind soul."), Ali Caldwell ("She is a freak of nature with her voice."), Courtney Harrell ("She would always give me such great advice, and I really care for her.") and Sa'Rayah ("I love her to death; she's amazing.") for "Proud Mary" -- a song that Gilman calls "an amazing power anthem." The three women sparkled onstage in glittering gold dresses and jumpsuits, while Gilman and Cuevas donned all-black ensembles; the song began as a slowed-down, soulful slow jam, then picked up into an all-out party.

Creedence Clearwater Revival first recorded "Proud Mary," written by the band's John Fogerty, in 1969, and became a major hit in the U.S. The Turners' cover of the song, released in 1970, turned the tune into a funky, soulful song, and reached the Top 5 on both the all-genre Billboard Hot 100 and Hot R&B / Hip-Hop Songs charts; it also won a Grammy for Best R&B Vocal Performance By a Group.

Gilman skyrocketed to stardom following the release of “One Voice,” his debut single, in 2000; he was 11 years old at the time, making him the youngest country artist to ever earn a Top 40 hit. Gilman’s album of the same name earned double-platinum status, but his following singles and albums did not achieve the same level of success. In November of 2014, Gilman revealed that he is gay — and called out the country music industry to support LGBTQ artists. When auditioning for The Voice, Gilman landed on Adam Levine's team during the blind auditions.
